Abstrakt: Population of Trichuris sp. isolated from Hystrix cristata was analyzed based on morphological, biometrical characteristics and mitochondrial (cox1, cob, rrnL) and ribosomal (ITS1) (rDNA) region sequences. Morphological and biometrical results revealed that Trichuris sp. from H. cristata present a high similarity with Trichuris landak from Hystrix javanica and less similarity with other Trichuris species from porcupine species (Trichuris hystricis, Trichuris lenkorani and Trichuris mettami). The lack of molecular data corresponding to Trichuris species that parasitize the porcupine (genus Hystrix and Atelerix) has not allowed a comparative molecular or phylogenetic study. Molecular analyses revealed the existence of two different haplotypes that did not correspond to different morphospecies. Relationships among Trichuris sp. from H. cristata and other Trichuris spp. have been resolved by molecular sequence data in this study. Thus, the combined analysis of one ribosomal and three mitochondrial markers revealed a sister relationship between whipworms parasitizing porcupine and other Trichuris spp. from rodents and canids and separated from the rest of Trichuris spp. from other hosts species. It is necessary accurate information on the possible zoonotic behavior of different Trichuris species for health workers to improve existing control measures. Thus, it is necessary to increase the studies of integrative taxonomy on Trichuris spp. based on morphological, biometrical and molecular data, which will inevitably contribute to our knowledge on the etiology of trichuriasis.
